I understand where IMWhizzle is coming from.
3D at home is definitely dead and has been for a few years. 3D Tvs are now a thing of the past. You mention Sony specifying it as a 3D release, but we don't know who wanted this 3D release. Probably it was the MJ Estate, not Sony. Sony themselves stopped manufacturing 3D TVs at the beginning of 2017, as did LG. In fact they were the last major manufacturers to stop doing so. Samsung stopped making them in 2016! TV Channels broadcast in 3D are also in the past. In the USA the major channels stopped being broadcast in 3D in 2012/2013. In the UK Sky stopped a few years ago.
It's slightly better in the cinema where some films are still being release in 3D and 3D tickets are priced at a premium, but it's not much better. Cinema 3D is dying too. The number of movies filmed in 3D has reduced greatly in the last few years, and so has the market share for 3D tickets sales. Most '3D' films, including those from Sony, are now actually being filmed in 2D and being converted to 3D in post-production. 3D is an after thought now. When films are shown to the press these days they show the 2D version, not the 3D version. I'm sure that will for James Cameron next Avatar film, but I don't see a resurgence for 3D coming off the back of those films.
As for Thriller 3D, well it has come years too late. I'm not saying the MJ Estate should have released it when Avatar kicked off the latest 3D 'revolution' in 2009/2010 but they should have definitely released it before 3D started its decline in 2012/2013 for maximum impact. When it was announced last year, sure it was news worthy but I guarantee most people just thought "so what?". The MJ fans will love it of course, and if I can find a cinema showing it in 3D I will go. But the majority in the general public simply don't care about 3D now. As IMWhizzle said, it's all about UHD/4K these days and luckily I'm sure The MJ Estate covered that base too. After all, while rescanning the original film, converting to 3D etc, why wouldn't they create a UHD version???
